BRACELET.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed September 11,1905. Serial No. 277.923.

To all whom it 77u01/ concern:

Be it known that I, VALFRID WALLEN- THIN, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Bracelets, of which the following is a specification.

This invention has reference to an improvement in bracelets, and more particularly to an improvement in concealed hinges for bracelets.

The object of my invention is to improvethe construction of a concealed hinge for bracelets whereby a stronger and more durable concealed hinge is constructed than has heretofore been done.

My invention consists in the peculiar and novel construction of a concealed hinge for bracelets, with details of construction, as will be more fully set forth hereinafter.

Figure l is a side view of a bracelet provided with my improved concealed hinge and showing the bracelet in the closed position in full lines and in the open position in broken lines. Fig. 2 is an enlarged detail sectional view of the hinge end of the bracelet looking at the outside face of the hinge. Fig. 3 is an enlarged detail sectional view taken on line X X of Fig. 2 through the hinge and adjacent portion of the bracelet and showing the hinge in the closed position 5 and Fig. 4 is a detail sectional view similar to Fig. 3, taken on line Y Y of Fig. 2 and showing the hinge in the open position.

In the drawings, a indicates the upper semi-oval half, b the lower semi-oval half, and c the concealed hinge, of my improved bracelet.

The semi-oval halves a and b are constructed from a tube, which is oval in cross-section. The upper half a has the end a for the hinge andthe end a2. The lower half l) has the end b for the hinge and the end b2. The ends c and b and theends a2 and b2 coincide when the bracelet is closed. The ends a2 and b2 may be provided with any of the well-known forms of catches adapted to hold the ends together when the bracelet is closed.

My improved concealed hinge c consists of the members d and e. These members d and e are curved to conform to the contour of the bracelet and shaped to iit in the ends a and b', in which they are secured by solder or other means. The member d of the hinge has the beveled end d, the two semicircular grooves d2 d2, and the semicircular cross-bar d3. The semicircular grooves d? d2 extend inward from the beveled end d and outward through the outer face of the member, forming central and outer webs, as shown in Fig. 2. Semicircular notches are formed centrally in the webs and the semicircular crossbar d3 secured to the webs in the notches by solder. The member e of the hinge has the beveled end e', from which the two semicircular iingers e2 e2 extend. These iingers are spaced and shaped to fit into the semicircular grooves d2 d2 in the member d under the cross-bar d3, which forms the pintle of the hinge. A groove e3 is formed lengthwise in the inner face of one of the fingers e2, and a teat Z4 stamped up from the bottom of the coinciding groove (Z2 into the groove e, This teat d* acts on the bottom of the groove c3 in the finger e2 as a stop to limit the opening movement of the bracelet, as shown in Fig. A. The beveled ends d and e of the hinge coincide when the hinge is closed, as shown in Fig. 3. By this construction the end d protrudes from the end b ofthe bracelet, practically closing the opening between the ends a and t of the bracelet when the bracelet is opened, as shown in Fig. 4.

In the operation of my improved concealed hinge the semicircular fingers e2 e2 on the memberA e have a circular reciprocating movement in the simicircular grooves d2 d2 in the member (Z under the cross-bar d3, and this movement is limited in closing the hinge by the beveled ends d and e and in opening the hinge by the teat d4, acting as a stop on the bottom of the groove e3 in the Jringer e2.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a hinged bracelet, a concealed hinge comprising aimember having a beveled end, semicircular grooves extending inward from the beveled end and outward through the outer face of the member forming central and side webs in which are central semicircular notches and a semicircular cross-bar secured to the webs in the notches, and a member having a beveled end, semicircular fingers extending from the beveled end and adapted to iit into the semicircular grooves in the first member under the semicircular bar, means for limiting the opening move- IOO ment of the hinge, and means for securing the members of the hinge in the bracelet, as described.

2. A concealed bracelet-hinge comprising a member d having the beveled end d', the seinicircular grooves d2 d2 extending inward from the beveled end d and outward through the outer face of the member forming central and side webs in which are central semicircular notches, a semicircular cross-bar d3 secured to the webs in the notches, a member e having the beveled end e, the semicircular fingers e2 e2 extendingI from the beveled end e and adapted to it into the semicircular grooves Z2 d2 in the member d under the bar cl3, the groove e3 in a finger e2, the teat d* on the member d adapted to enter the groove e3 in the finger e2 and 'form a stop, and means for securing the members Z and e of the hinge in a bracelet, as described.

3. The combination with a tubular half e having the end d and the tubular half I) having the end b of a bracelet, of a concealed hinge c composed of the members d and e,

the member (Z having the beveled end d, the seniicircular grooves d2 Z2 extending inward from the beveled end d and outward through the outer face of the member forming central and side Webs in which are central semicircular notches, a semicircular cross-bar d3 secured to the webs in the notches, the me1nber e having the beveled end d, the semicircular .fingers e2 e2 extending from the beveled end e and adapted to lit into the semicircular grooves d2 d2 in the member d, the groove c3 in a finger e2, the teat d4 on the member d adapted to enter the groove e3 in the iinger e2 and form a stop, and mea-ns for securing the members d and e of the hinge in the ends a and b of the halves a and Zi of the bracelet, as described. i

In testimony whereor1 I have signed my name to this specilication in the presence of two subscribing witnesses.
